Answer:

\sf2 \cdot \cfrac{7(3 {}^{2}) }{3}  = \boxed{ \bf 42}

Step-by-step explanation:

Given expression:

\sf2 \cdot \cfrac{7(3 {}^{2}) }{3}

To :

  • Evaluate the expression.

Solution:

Let's use PEMDAS for evaluating.

  • P stands for Parentheses
  • E for exponents
  • M for multiplication
  • D for Division
  • A for addition
  • S for subtraction

\sf2 \cdot \cfrac{7(3 {}^{2}) }{3}

\rightarrow 2 \times  \cfrac{7(9)}{3}

\rightarrow \: 2 \times  \cfrac{63}{3}

\rightarrow \:  \cfrac{2 \times  \cancel{63}  \:  \: {}^{21} }{ \cancel3 \:  \:  {}^{1} }

\rightarrow2 \times 21

\longrightarrow \sf \: 42

<u>Hence we can conclude:</u>

\sf2 \cdot \cfrac{7(3 {}^{2}) }{3}  = \boxed{ \bf 42}

Answer:

42

Step-by-step explanation:

We use (BODMAS) :

Brackets

Order/Index

Division

Multiplication

Addition

Subtraction

Now we do bracket first :

7(3²) = 7(9) = 63

Now we do division :

63÷3 = 21

Now we do multiplication :

2 × 21 = 42

Hope this helped and have a good day
