x^-5 = x to the power of negative 5
Step-by-step explanation:
Which of these is equivalent to 1 over x to the power of 5 ?
Mathematically this is expressed as
(1/x)⁵
We have a rule when it comes to expressing power
(1/a)^b = a^-b
Hence, applying this rule to our question
(1/x)⁵ = (1/x)^5
= x^-5
This is written in words as:
x to the power of negative 5
Answer:
£2.00
Step-by-step explanation:
Badly worded, as they oftena are! But to me it means
30% spent
60% saved (I.e also taken away and put somewhere else)
10% leftover equals 20p
So 20p equals 10% of what she originally had, so 100% must be £2.00, does that make sense?
