Answer:
24.3
Step-by-step explanation:
Here we need to evaluate,
[tex]\longrightarrow 3^3 +14.7\div 7-(1.2\times 4)[/tex]
First of all we need to know about BODMAS , which stands for ,
- B = Brackets
- O = of
- D = division
- M = multiplication
- A = Addition
- S = Subtraction
This means first we need to solve brackets , then of , then division , then multiplication, then addition and finally subtraction.
In the given questions, firstly solve the terms inside the brackets ,
[tex]\longrightarrow 3^3 +14.7 \div 7 -(1.2\times 4)[/tex]
Multiply 1.2 and 4 ,
[tex]\longrightarrow 3^3+14.7\div 7-(4.8) [/tex]
Now perform division , that is divide 14.7 by 7
[tex]\longrightarrow 3^3 + 2.1 - 4.8 [/tex]
Simplify 3³ .
[tex]\longrightarrow (3)(3)(3)+2.1-4.8= 27+2.1-4.8[/tex]
Add ,
[tex]\longrightarrow 29.1 -4.8[/tex]
Finally subtract,
[tex]\longrightarrow \underline{\underline{\boldsymbol{ 24.3 }}}[/tex]
And we are done!
