Question

Simplify: (-1/3+1/9) x 4^2 + 5/18

Answer 1

-59/18

Answer 2

(-(1)/(3)+(1)/(9))*4^(2)+(5)/(18)

Combine (1)/(9)-(1)/(3) into a single expression by finding the (LCD).
The LCD of 1/9-1/3 is 9.

(-(2)/(9))*4^(2)+(5)/(18)

Squaring a number is the same as multiplying the number by itself (4*4). In this case, 4 squared is 16.
(-(2)/(9))*16+(5)/(18)

Multiply 16 by each term inside the parentheses.
-32/(9)+5/(18)

Combine 5/18-32/9 into a single expression by finding the least common denominator , The LCD of 5/18-32/9 is 18.
-59/18
