Question

7³·7⁻²
2:2⁻²
(3⁻¹)²
(5⁻²)⁻¹
8⁻²·4³
10°:10⁻³
10⁸·10⁻⁵·10⁴
3⁶·(3⁻²)⁻⁴

Answer 1

7^3*7^-2=7^3+(-2)=7^1=7
2/2^-2=2^1/2^-2=2^1-(-2)=2^3=8
(3^-1)^2=3^-1*2=3^-2
(5^-2)^-1=5^-2*-1=5^2=25
8^-2*4^3=(1/8^2)*4^3
10^0/10^-3=10^0-(-3)=10^3=1000
10^8*10^-5*10^4=10^8+(-5)+4=10^7=10000000
3^6*(3^-2)^-4=3^6*(3^-2*-4)=3^6*3^8=3^6+8=3^14
