PEMDAS

______________________________________

PEMDAS RULE:

  • In finding the equal using the PEMDAS rule, Parenthesis is given first, then Exponent, Multiplication and Division left to right, Addition and Subtraction left to right.

1.) In 4³ ÷ (5 + 3) ² = N, What is the value of N.

  • \boxed{\bold{\red{D. \: 1}}}

  • \bold{{4}^{3} \: \div \: {(5 \: + \: 3)}^{2} \: = \: N }
  • \bold{{4}^{3} \: \div \: {8}^{2} \: = \: N }
  • \bold{64 \: \div \: {8}^{2} \: = \: N }
  • \bold{64 \: \div \: 64 \: = \: N }
  • \boxed{\bold{1 \: = \: N }}

2.) Evaluate (2 + a)² - 2 x b when a = 3 and b = 5

  • \boxed{\bold{\purple{D. \: 15}}}

  • \bold{{(2 \: + \: a)}^{2} \: - \: 2 \: \times \: b }
  • \bold{{(2 \: + \: 3)}^{2} \: - \: 2 \: \times \: 5 }
  • \bold{{5}^{2} \: - \: 2 \: \times \: 5 }
  • \bold{25 \: - \: 2 \: \times \: 5 }
  • \bold{25 \: - \: 10 }
  • \boxed{\bold{15}}
