If you mean 3,254^3 it would be 3,254 x 3,254 x 3,254 = 3.445503106x10^10 or 3.4455031060
Answer:
7 . 4 + 6 - 12 : 4 = 31
Step-by-step explanation:
* To solve this problem lets revise the order of operations in
mathematics
- The operations are:
# Addition
# Subtraction
# Multiplication
# Division
# Exponentiation
# Grouping ⇒ Parenthesis or brackets
- The order of these operations is:
# Parenthesis
# Exponents
# Multiplication and Division which comes first from left to right
# Addition and Subtraction which comes first from left to right
- There is a word made from the first letter of each operation
PEMDAS to remember the order of operations
* Lets solve the problem
∵ 7 . 4 + 6 - 12 : 4
∵ The (.) means multiply the numbers
∵ The symbol (:) means divided the numbers
∴ At first multiply 7 by 4 and divide 12 by 4
∴ (7 × 4) + 6 - (12 ÷ 4)
∴ 28 + 6 - 3
∵ Addition comes before subtraction from the left
∴ (28 + 6) - 3
∴ 34 - 3 = 31
∴ 7 . 4 + 6 - 12 : 4 = 31
Answer:
"The expression will always equal m" is true about the quotient of ÷
Step-by-step explanation:
Let us solve the question
∵ The expression is ÷
→ In the division of fractions, we change the division to multiplication
and reciprocal the fraction after the division sign
∵ The reciprocal of is
∴ ÷ = ×
→ In the multiplication of fractions, we can simplify the terms in
the numerators by the terms in the denominators
∵ There is n in the numerator and denominator
∴ Cancel n up and down
∴ × =
∴ × = m
∴ ÷ = m
∴ The quotient is m
∴ The expression will always equal m
Answer:
Total monthly expenditure = Rs 115,500
Total savings = Rs 49,500
Step-by-step explanation:
Total salary = Rs 165000.
Food = 20%
= 20/100 × Rs 165,000
= 0.2 × 165,000
= Rs 33,000
House rent = 25%
= 25/100 × Rs 165,000
= 0.25 × 165,000
= Rs 41,250
Fuel = 10%
= 10/100 × Rs 165,000
= 0.1 × 165,000
= Rs 16,500
Miscellaneous = 15%
= 15/100 × Rs 165,000
= 0.15 × 165,000
= Rs 24,750
Total monthly expenditure = food + house rent + fuel + miscellaneous
= Rs 33,000 + Rs 41,250 + Rs 16,500 + Rs 24,750
= Rs 115,500
Total monthly expenditure = Rs 115,500
Total savings = Total salary - Total expenditure
= Rs 165,000 - Rs 115,500
= Rs 49,500
Total savings = Rs 49,500
