Write the expression as a monomial in its standard form:

(-3a^7b^2)^4 * 1/27 *ab

an exponent to a power means multiply the exponents

-3^4 a^(4*7) b^*(2*4) * 1/27 *ab

81 a^ 28 b^8 * 1/27 * ab

combine like terms

81/27 a^ 28 *a b^8 b

when multiplying, add the exponents

3 a^ (28+1) b^(8+1)

3 a^29 b^9

because they could drop even lower..

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
