Answer:

We can evaluate this using the order of operations. To begin with, we start with the (2/3)^2 since it is an exponent and in parenthesis. This comes to 4/9 because we multiple 2 times 2 to get the numerator and 3 times three for the denominator. Then we multiply by 5. This gives us 20/9 because we are multiplying by 5/1. We use the same process as above. We can express 3 as 3/1 or 27/9. 20/9-27/9 is -7/9. So the answer is -7/9.

Answer:

-7/9

Explanation:


5((2)/(3) )^(2) -3\\\\=5((4)/(9) )-3\\\\=(20)/(9) -3\\\\=(20)/(9)-(9*3)/(9) \\\\=(20)/(9) -(27)/(9) \\\\=(20-27)/(9) \\\\=-(7)/(9)
