How do i use Scientific notation on these problems? Because I don't know...

Answer:

Simplify the problems first

Step-by-step explanation:

Before you can convert it to scientific notation, you should simplify it first.

#1 for example:

$(4 \times 10^5)^2\\$

Use PEMDAS to solve the equation:

$(4 \times 10^5)^2\\= 400000^2\\= 160000000000$

So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be $1.6 \times 10^{11}$ since there are 11 places after the decimal.

An equation is formed of two equal expressions. The value of x for which the equation has a solution is 1.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution for 10x+16=6x+20 is,

10x + 16 = 6x + 20

10x - 6x = 20 - 16

4x = 4

x = 1

Hence, the value of x for which the equation has a solution is 1.
