Given Question:-

Express 750×900 as a product of its prime factors using exponents

Solution:-

Given that

750×900

750 can be written as

750= 2×3×5×5×5

900=2×2×3×3×5×5

Now,

750×900

=>2×3×5×5×5 ×2×2×3×3×5×5

=>(2×2×2)×(3×3×3)×(5×5×5×5×5)

=>2^3×3^3×5^5

Answer:-

750×900=2^3×3^3×5^5

Given:-

Juhi bought a car for Rs. 560000 and sold it for

Rs. 420000.

To find:-

Find her loss and find loss percentage

Solution:-

Cost price of the car (CP)=Rs. 560000

Selling Price of the car (SP)=Rs. 420000

560000>420000

Cost Price > Selling Price

We know that if Cost Price is greater than Selling Price then we will get loss

Loss = Cost Price - Selling Price

=>Loss = 560000-420000

=>Loss = 140000

Now we know that

Loss percentage = (Loss / CP) × 100

=>L% =( 140000/560000)× 100

=>L% = (14/56)×100

=>L% = (1/4)×100

=>L% = 100/4

=>L% = 25

Loss percentage = 25%

Answer:-

Loss for the given problem is Rs. 140000

Loss percentage for the given problem is 25%

Used formulae:-

• Loss = Cost Price - Selling Price
• Loss or Profit is calculated on Cost Price
• Loss percentage = (Loss/CP)×100
