Answer:
[tex] \sf2 \cdot \cfrac{7(3 {}^{2}) }{3} = \boxed{ \bf 42}[/tex]
Step-by-step explanation:
Given expression:
[tex] \sf2 \cdot \cfrac{7(3 {}^{2}) }{3} [/tex]
To :
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
[tex] \sf2 \cdot \cfrac{7(3 {}^{2}) }{3} [/tex]
[tex] \rightarrow 2 \times \cfrac{7(9)}{3}[/tex]
[tex] \rightarrow \: 2 \times \cfrac{63}{3} [/tex]
[tex] \rightarrow \: \cfrac{2 \times \cancel{63} \: \: {}^{21} }{ \cancel3 \: \: {}^{1} } [/tex]
[tex] \rightarrow2 \times 21[/tex]
[tex] \longrightarrow \sf \: 42[/tex]
Hence we can conclude:
[tex] \sf2 \cdot \cfrac{7(3 {}^{2}) }{3} = \boxed{ \bf 42}[/tex]
