Question

which of the following is equal to 4 raise to power15 + 8 raise to power 10​

Answer 1

Answer:

2^31

Step-by-step explanation:

${4}^{15} + {8}^{10} \\ \\ \\ = { {2}^{2} }^{15} + { {2}^{3} }^{10} \\ \\ \\ \\ = {2}^{30} + {2}^{30} \\ \\ \\ = 2 \times {2}^{30} \\ \\ \\ = {2}^{31}$

Answer 2

Answer:

2^60/4^30

Step-by-step explanation:

4^15+8^10

(2^2)^15+(2^3)^10

((a^m)^n)=a^mn

2^30+2^30

(a^m +a^n = a^m+n)/(a^m+b^m=(a×b)^m)

so, 2^30+30=2^60/

(2×2)^30=4^30
