Question

2(1+3)^3-5^2 help me plsss 100 points given

Answer 1

To solve this expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction), which tells us to perform the operations in the following order:

Parentheses

Exponents

Multiplication and Division (from left to right)

Addition and Subtraction (from left to right)

Using PEMDAS, we can simplify the expression as follows:

2(1+3)^3 - 5^2

= 2(4)^3 - 25 // inside the parentheses, 1+3 = 4

= 2(64) - 25 // 4^3 = 4 x 4 x 4 = 64

= 128 - 25

= 103

Therefore, the solution to the expression 2(1+3)^3-5^2 is 103.

Answer 2

First, we need to evaluate the exponent 3 of the expression inside the parentheses:

(1+3)^3 = 4^3 = 64

Next, we can simplify the expression by applying the order of operations (PEMDAS):

2(1+3)^3-5^2 = 2(64) - 25

Now, we can continue simplifying:

2(64) - 25 = 128 - 25

Finally, we can evaluate the subtraction:

128 - 25 = 103Therefore, 2(1+3)^3-5^2 = 103.
