Answer:

1) 1.96

2) 6

3) 4/3

Explanation:

think of exponents as repeated multiplication. the exponent is how many times you're going to multiply the number itself by.

1)
1.4^(2) is really just 1.4 * 1.4, which you can solve by long multiplication or a calculator to get 1.96

2) for this one, you can rewrite the expression as a fraction. you'll also want to use PEMDAS, starting with the parentheses


(300)/( 2(0.5+4.5)^(2))\\\\(300)/(2*(5)^2)\\\\(300)/(2*25) \\\\(300)/(50) = 6

3)
((1)/(2))^(3) = (1)/(2) *(1)/(2) *(1)/(2) = (1)/(8) \\

you can rewrite the division as a fraction again, only this time. you can change the subtraction to the reciprocal of the denominator


(1)/(3) / (2*(1)/(8) )= (1)/(3) / (1)/(4) = (1)/(3) * 4 = (4)/(3)

hope this helped!
