[adot]

Add the exponents => 4+(-4)=0
x^0=1
The answer is 1

[Info_rare]

You used three operations, the fourth one is sqrt(a^n) of index m will be a^(n/m)

[gvenagas]

Laws of exponents are really useful when dealing with decimal numbers!

[DrAce]

The last one is x^0 but that is equal to 1 so the answer is 1

[popff]

note: this only works if they have the same base

[Vita.Terrae]

If the base doesn't have an exponent, , , the coefficient is understood as 1 then you gotta add up all of the exponents not multiply

[ilusion]

Don’t memorise these laws see why they are true it’s makes it much easier to remember
For example to see why a^0=1
A^1*a^0=a or a^1+0
Because of identity property a^0 has to be 1

[RagelKinda]

X4 . X-4

= 4+(-4) = 0
So it's just x

[keshaunastewart]

This stuff and the fractions with exponents are so hard for me

[Dtmsst]

She was good in math cause she got many X's 😮😮😮😮😮
