Count how many decimal places you need to move to the right until you get to:

1.203 and then multiply that by 10 raised to the power of the number of places you moved the decimal point...in this case it had to move 10 places so:

WORTH BRAINLIST!!!<br> What is the value of the expression 2 + 3^2 ⋅ (3 − 1)? 20 22 23 32
Wittaler [7]

Answer:

You have to use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction), and solve in that order. Your question is:

2 + 32 ⋅ (3 − 1)

First, solve the Parentheses part of the question. 3-1 is 2. Your question is now:

2+32*2

Now, solve the multiplication part of the question. 32*2 is 64. Your question is now:

2+64

This is now an easy problem to solve.

The answer is 66.

Hope this helps! :)
