Question

1)(a^1.5)2 черта 3 2)b^-0.2 :b^-0.7

Answer 1

А:3+4+5×6×9:0.24×4×44×

Answer 2

1. To simplify the expression (a^1.5)2/3, we can use the property that (a^m)^n = a^(m*n), where "m" and "n" are any real numbers.

So, we have:

(a^1.5)^(2/3) = a^(1.5 * 2/3) = a^(1.0) = a

Therefore, (a^1.5)2/3 simplifies to "a".

2. To simplify the expression b^-0.2 : b^-0.7, we can use the property that a^m / a^n = a^(m-n), where "a" is any non-zero number and "m" and "n" are any real numbers.

So, we have:

b^-0.2 : b^-0.7 = b^(-0.2 - (-0.7)) = b^0.5 = √b

Therefore, b^-0.2 : b^-0.7 simplifies to "√b".
