Question

10^-1+5^2. (2/3)^-1+(-1,7)^0-2^3

Answer 1

10^-1+5^2=0,1+25=25,1. (2/3)^-1+(-1,7)^0-2^3=1,5+1-8=2,5-8= -5,5.

Answer 2

Let's break down the expression and solve it step by step:

10^-1 means 1/10, so:

1/10 + 5^2 = 1/10 + 25 = 25/10 = 5/2

(2/3)^-1 means the reciprocal of 2/3, which is 3/2:

(2/3)^-1 + (-1,7)^0 = 3/2 + 1 = 5/2

(-1,7)^0 means any number to the power of 0 is 1, so:

(-1,7)^0 - 2^3 = 1 - 8 = -7

Therefore, the final result is -7.
