Question

please tell please guys​

Answer 1

Answer:

2(5/2) - 2(3/2)

When we have fractional exponents, we have radical terms.

Apply these rules:

x(m / n) = n√(xm)

x(n / n) = n√(xn) = x

√(25) - √(23)

Break down the radical terms by their f

actors.

√(22) √(22) √(2) - √(22) √(2) =

2 * 2 * √(2) - 2 * √(2) =

4√2 - 2√2 =

2√2

Putting this result in exponent form,

2 * 2(1/2) =

2(3/2)what is the answer of 2+(-5)

ans:2+(-5)=-3
