Ummm if I understand the question there will be symbols.

Addition is +
Subtraction is -
Multiplication is * or x
Division is /

If you have an expression use PEMDAS like ChrisR described.

PEMDAS is very helpful to remember when thinking of order of operations. Parentheses, Exponents, Multiply, Divide, Add, then Subtract. Always in that order. 

If you are talking about something more specific you may want to give a bit more information.

Please can someone express √5 as a fraction? ​
VashaNatasha [74]
<h2>Answer:</h2>

<em>SInce this continued fraction does not terminate, we can tell that √5 cannot be represented as a terminating fraction - i.e. a rational number. So √5 is an irrational number a little smaller than 214=94 . For better rational approximations you can terminate the continued fraction after more terms.</em>

hope this help!

the exponent expression 2⁸ has a value of 256.write two other exponential expressions that have the value of 256. explain how yo
Flura [38]

The other two expressions that have value of 256 is 4⁴ and 16².

Given the exponent expression 2⁸ has a value of 256.

We want to write two other exponential expressions that have value 256.

The given expression is 2⁸=256

The above expression can be written as

2×2×2×2×2×2×2×2=256

By using the Associative property of multiplication, we can write them as

(2×2)×(2×2)×(2×2)×(2×2)=256

4×4×4×4=256

4⁴=256

and it can also be written as by using the associative property of multiplication again and get

(2×2×2×2)×(2×2×2×2)=256

16×16=256

16²=256

Hence, the two other exponential expression of 256 other than 2⁸ is 4⁴ and 16².
