Simplify each expression. give your answer using positive exponents. a) 8^(-2) b) 1/3^(-3) c) 6^(-12)∙6^8∙6^0

A) 8^(-2) = 0.015625

 make the -2 positive and make the 8 a denominator with 1 as a numerator

= 1/8^2

B) 1/3^(-3) = 27
 = 3^3 = 27

C) 6^(-12) * 6^8 * 6^0 = -12+8 = -4 = 6^-4

same as A turn the 4 into a positive and put 6 in a fraction

= 1/6^4

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
