53
Step-by-step explanation:
Given :
[tex]3(a+3b)-4[/tex]
[tex]a=4\\b=5[/tex]
To Find : value of the given expression.
Solution :
[tex]3(a+3b)-4[/tex]
Putting value of a and b
⇒[tex]3(4+3*5)-4[/tex]
Solving this we will use BODMAS rule : According to this rule we need to follow the sequence for solving mathematical expressions
B - Bracket
O- Of
D - Division
M- Multiplication
A - Addition
S- Subtraction
Following this sequence we will solve the given expression
⇒[tex]3(4+15)-4[/tex]
⇒[tex]3(19)-4[/tex]
⇒[tex]57-4[/tex]
⇒[tex]53[/tex]
Thus, The value of the expression [tex]3(a+3b)-4[/tex] is 53
