Math Problem Statement

Hasil dari 4^2 : 2^3 x 3^2 adalah ....

Solution

The question asks for the result of the expression 42÷23×324^2 \div 2^3 \times 3^2.

Let's break it down step-by-step:

Step 1: Calculate each part of the expression

  • 42=164^2 = 16
  • 23=82^3 = 8
  • 32=93^2 = 9

Step 2: Substitute these values back into the expression

16÷8×916 \div 8 \times 9

Step 3: Perform the division and multiplication from left to right

  • 16÷8=216 \div 8 = 2
  • 2×9=182 \times 9 = 18

Thus, the result of the expression is 18.

The correct answer is E (18).
