Add or subtract as indicated. 25.32 + 109.2 + 8.574

Evaluate each expression. (4-2³)(-2+√25)

Perform the indicated computations. Write the answers in scientific notation. If necessary, round the decimal factor in your scientific notation answer to two decimal places. $(4.3\times {10}^8)(6.2\times {10}^4)$

Simplify using properties of exponents. $\frac{20x^{\frac{1}{2}}}{5x^{\frac{1}{4}}}$

Let U = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}, M = {0, 2, 4, 6, 8}, N = {1, 3, 5, 7, 9, 11, 13}, Q = {0, 2, 4, 6, 8, 10, 12}, and R = {0, 1, 2, 3, 4}.Use these sets to find each of the following. Identify any disjoint sets. ∅ ∩ Q
