Question

(2^3)^7 (2^-9)^2 how do i put that in exponential form​

Answer 1

Answer:

2³ = 8

Step-by-step explanation:

According to the laws of exponents, when raising a power to another power, you need to multiply the exponents.  After you multiply each set of exponents by the additional power, then it become a multiplication problem where the base is the same.  When multiplying exponents with the same base, you keep the base and add the exponents:  

$(2^{3})^{7}*(2^{-9})^{2}=2^{21}*2^{-18}=2^{21+-18}=2^{3}$
