Answer:

0.00024

Step-by-step explanation:

If the exponent on ten is positive, then move the decimal point to the right by that number.

If the exponent on the ten is negative(which in this case it is), then move the decimal point to the left by that amount(4).

Answer:

The value is 2.4\times 10^{-4}=0.00024 in standard notation.

Step-by-step explanation:

Given : The number in scientific notation 2.4\times 10^{-4}

To find : Convert the number into standard notation ?

Solution :

The number in scientific notation 2.4\times 10^{-4}

Standard notation is writing number into larger way by expanding all powers,

2.4\times 10^{-4}=\frac{24}{10}\times \frac{1}{10000}

2.4\times 10^{-4}=\frac{24}{100000}

2.4\times 10^{-4}=0.00024

The value is 2.4\times 10^{-4}=0.00024 in standard notation.

Simplify (step by step too)
koban [17]

The simplified form of the expression √( 45 x⁸ w⁷ ) is 3x⁴w³√(5w).

<h3>What is the simplified form of the expression?</h3>

Given the expression in the question;

√( 45 x⁸ w⁷ )

First, factor out 9 from 45

√( 9(5) x⁸ w⁷ )

√( 3²(5) x⁸ w⁷ )

Rewrite x⁸ as (x⁴)²

√( 3²(5) (x⁴)² w⁷ )

Rewrite w⁷ as ( w⁶ × w )

√( 3²(5) (x⁴)² ( w⁶ × w ) )

Rewrite w⁶ as (3³)²

√( 3²(5) (x⁴)² (w³)² × w  )

We can now take the square roots of all the terms with a power of 2 and take them out of the square root

(3)(x⁴)(w³)√(5w)

3x⁴w³√(5w)

Therefore, the simplified form of the expression √( 45 x⁸ w⁷ ) is 3x⁴w³√(5w).

Bogdan [553]
150 g flour for 12 cakes
x g flour for 30 cakes
x = (150 x 30) : 12 = 375 g of flour

another method:

150 flour for 12 cakes
??? for 30 cakes

30 : 12 = 2.5
150 x 2.5 = 375 g flour
