To the nearest hundredth the correct answer is 4.05, but you're basically right
Answer:
Step-by-step explanation:
We have several properties of exponents in use here. The two that are used are:
<em>(Exponents with the same base that are being multiplied together can have the exponents added)</em>
<em>(A base raised to a power, and then raised to another power means that you can multiply the exponents to get the same result as doing inside operations and then outside operations)</em>
<em />
Let's apply it!
First, let's simplify what's inside the parenthesis.
<em>(Remember, they have the same base of "x", so we can add the exponents)</em>
= =
Now we have . Let's use the second rule.
=

Answer:
£290.70
Step-by-step explanation:
Number of notes of $50 = 5
Total value = 50 × 5 = $250
Number of notes of $20 = 2
Total value = 20 × 2 = $40
Number of notes of $10 = 7
Total value = 10 × 7 = $70
Number of notes of $5 = 3
Total value = 5 × 3 = $15
Total value of all notes with John = 250 + 40 + 70 + 15
= $375
Since, $1.29 = £1
Therefore, $1 = £
Therefore, $375 = £
= £290.70
X = 2/3 makes the equation true.
Answer: x = 2/3
