Lna^b = blna

let y = lne^e

so y = lne^e = e lne  

lne =  1 

y = e which is a constant (Euler's number) ~= 2.718 

For Euler's number estimating methods request in a comment.

2.5 kg cost £1.40<br><br>work out the cost of 4.25kg
Mkey [24]

Calculating the cost of 4.25 kilogram(kg) is £2.38, by multiplying it by 4.25 kg by 1 kg.

<h3>Cost</h3>

Costs are the expenses incurred in the manufacture, marketing, or preparation of a good or asset for regular use. In other terms, it's the cost incurred to produce a good, buy inventories, sell goods, or prepare equipment for use in a commercial activity.

Given,

2.5 kg cost  £1.40 i.e,

2.5 kg = £1.40

For 1 kg= \frac{1.40}{2.5}

= £0.56

To find the cost of 4.25 kg:

Then,

1 kg = £0.56

4.25 kg = 0.56 x 4.25

= £2.38

£2.38 is the cost of 4.25kg after calculating it.

18, 26, 34, 42, find the 52nd term and the explicit formula
daser333 [38]
We have 26 - 18 = 8; 34 - 26 = 8; 42 - 34 = 8; (an arithmetic progression)
We use the formula an = a1 + (n-1)x8 (the explicit formula)
So, an = 18 + (n-1)x8 ;
Then, an = 8n + 10;
Finally, a52 =  8x52 + 10 = 426 (the 52nd term);

Which is not equivalent to the rest 13/20 66% 195/300 0.6500
Ganezh [65]
Hey there! :)

Let's change all the fractions and percents to decimal.
_____________________________________________________________

When changing fractions to decimal, divide the numerator by the denominator
When changing percents to decimal, remove the % sign and move the decimal to places to the left.
_____________________________________________________________

13 ÷ 20 = 0.65
66% = 0.66
195 ÷ 300 = 0.65
0.6500 = 0.65
_____________________________________________________________

The answer is 66% because it is the only one that isn't equivalent to 0.65

Hope this helps :)
