I want to know did I work these problems right
Multiply: (  6)²  4² = 36 – 16 = 20
Multiply
(  3) (  6 ) + ( 4 ) ( 2) = 18 + ( 8) = 188= 10
Multiply: (  3 ) ³  (  8) ( 2) =
(3) times 3 = 9
(8) times (2) = 16
9  16 = 25
25
Multiply: 9 ²  ( 6)² = 8136= 45

The first two are OK. The third is not. The fourth has the wrong sign.
"Multiply": (  3 )³  (  8) ( 2) =
The superscript 3 is an exponent.
(  3 )³ = (3)(3)(3) = 27
Subtract 16 from that.
Why do you start each operation with the word "multiply"? There are also other operaions involved (adding, subtracting and taking exponents)
