3a+b^{2}c

Answer 1

`\huge{ \fbox{ \sf{84}}}`

Explanation:

`\underline{ \sf{ \: Given}} :`

`\sf{a = 4 \: , \: b = 6 \: , \: and \: c \: = \: 2}`

`\underline{ \sf{To \: find}} : \sf{Value \: of \: the \: given \: expression}`

`\sf{ \: \bigstar{ \sf{ \: 3a + {b}^(2) c}}}`

`\text{ Step \: 1} : \sf{Plug \: the \: values \: of \: a \: b \: and \: c}`

`\mapsto{ \sf{3 \: * \: 4 \: + {6}^(2) \: * \: 2}}`

`\text{Step \: 2} : \sf{Evaluate \: the \: power : {6}^(2) }`

`\mapsto{ \sf{3 \: * \: 4 \: + \: 36 \: * \: 2}}`

`\text{Step \: 3} : \sf{Multiply \: the \: numbers : 3 \: by\: 4}`

`\mapsto{ \sf{12 + 36 \: * \: 2}}`

`\text{Step \: 4} : \sf{Multiply \: the \: numbers : 36 \: by \: 2}`

`\mapsto{ \sf{12 + 72}}`

`\text{Step \: 5} : \sf{Add \: the \: numbers : \: 12 \: and \: 72}`

`\mapsto{ \sf{84}}`

Note: Follow PEMDAS

Parentheses , Exponents , Multiplication , Division , Addition , Subtraction

Hope I helped!

Best regards! :D

Answer 2

Here,

a=4

b=6

c=2

Then,

`3a + {b}^(2) c \\ = 3 * 4 + {6}^(2) 2 \\ = 12 + 12 * 2 \\ = 24 * 2 \\ = 36`

Hence, The solution is 36.
