Evaluate the following. 7 3 7^3

we're asked to evaluate the following. And we're given here seven cubed or seven to the third power. So this means that I need to take seven and multiply it by itself three times. Seven times seven times seven. So in order to evaluate this, we now need to perform this multiplication. So we can start with just seven times seven. Seven times seven gives us 49. Then I need to take that 49 and multiply it by that remaining seven. Now 49 times seven, if you're able to use a calculator in your course, you can just type this right into your calculator. If not, you can perform this multiplication using whatever method you prefer. I'm gonna go ahead and set this up as 49 times seven, stacking them vertically to more easily perform this multiplication. So I'm gonna take seven times nine, which gives me 63. So I need to put my three down here, my six up at the top. Then I multiply seven times four, which gives me 28, and I need to add that six. So 28 plus six gives me 34. So that tells me that 49 times seven is 343, which gives me my final answer that seven cubed equals 343. If you have any questions, let me know, and let's keep practicing.

Verified step by step guidance

Identify the expression to evaluate: \$7^3$, which means 7 raised to the power of 3.

Recall that an exponent indicates repeated multiplication of the base. So, \$7^3$ means $7 \times 7 \times 7$.

Multiply the first two sevens: calculate $7 \times 7$.

Take the result from the previous multiplication and multiply it by 7 again to complete the exponentiation.

The final product after these multiplications is the value of \$7^3$.
