Your question equals 1/16 or 0.0625.
Answer:
<em>n = 6 </em>
Step-by-step explanation:
2.3 × 
= (1 × 10³)(2.3 × 
)
(1 × 10³)(2.3 × ) = (1)(2.3) × (10³)( ) = 2.3 × 
2.3 × = 2.3 × ⇒ 3 + n = 9 ⇒ <em>n = 6</em>
Answer:y=-1/2
Step-by-step explanation:
125=(1/25)^(y-1)
5^3=(5^(-2))^(y-1)
5^3=5^(-2(y-1))
The same base eliminate each other we then have
3=-2(y-1)
3=-2y+2
Collect like terms
2y=2-3
2y=-1
Divide both sides by 2
2y/2=-1/2
y=-1/2
Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.
Step-by-step explanation:
Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.
Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!
