The answer of that is called a compatible number. I hope this helps! :)
We have been given an expression
. We are asked to find the solution to our given expression expressed as scientific notation.
Let us simplify our given expression.
Using exponent property
, we will get:



Now to write our answer in scientific notation, we need our 1st multiple between 1 and 10. So we will rewrite our expression as:



Therefore, our required solution would be
.
Answer:its easy it the first one you had posted
Step-by-step explanation:
2 different possible ways if there is only 2 students.
To solve, you must use order of operations. The acronym used is BEDMAS (brackets, exponents, division/multiplication, addition/subtraction), which is the order you solve in.
F 20÷4x5
=5x5
=25
T 10+10÷2
=10+5
=15
F 6+4×5
=6+20
=26
<span>T 81÷9+2
=9+2
=11</span>
